Education lasts long. Since we were born, we are trying to learn more. Education includes three parts: education before school, school education and work training.
Education before school is the first stage. Often, in this period, we are children from 0 to 7 in China. This stage is very necessary. It's reported that at 0 to 3 people's intelligence develops fastest. At this stage we learn some basic knowledge to set up an interest of the world, nature and learning.
School education is the most important time in our life. It is the golden time. At this period we have enough ---- to support our learning. There are three stages such as: primary school, six years; middle school, six years and stay at university for four years. We spend 16 years at school in all. University has something important to do with our future, especially our work. We study professionally. We only choose the subject to learn which is different from middle school. School education teachers us a general idea about history, maths, politics, biology chemistry and soon. They are useful. 
After our school education is ended, we enter the third stage: work training. We use the knowledge we learn at school in our jobs, but we sometimes find that is not enough. So we must have a work training. This training lasts long. It's the longest. It is in the rest of our life. If not, we can't live and fall behind.
Of course, there are some differences and similar in these stages, but they are parts of education. Education as a lifelong process is needed in our developing work. It's just like the old Chinese sentence: Learn to the old.
